Thermal, Mechanical, and Degradation Properties of Nanocomposites Prepared using Lignin-Cellulose Nanofibers and Poly(Lactic Acid)

BioResources, 2014
A variety of nanocomposites were prepared using lignin-cellulose nanofibers (L-CNF) and poly(lactic acid) (PLA) via a solvent casting process. Acid hydrolysis and high-pressure homogenization processes were used to produce L-CNF from unbleached kraft ...

In-situ Green Synthesis of Gold Nanoparticles using Unbleached Kraft Pulp

BioResources, 2015
Facile green synthesis of gold nanoparticles (AuNPs) on cellulose fiber was successfully achieved by reducing chloroauric acid (HAuCl4·3H2O) by means of unbleached kraft pulp. A significant color change in pulp fiber indicating the in-situ formation of gold was observed with one-step synthesis in an autoclave.

Local Femtosecond Pulsed Laser Decoating of Superhydrophobic Paper Coating for Enhanced Fog Harvesting Efficiency

Advanced Materials Interfaces, Volume 12, Issue 17, September 8, 2025.
This study investigates the enhancement of water harvesting efficiency on superhydrophobic paper by introducing pinning structures using femtosecond laser ablation. Surface wettability and water collection performance are evaluated through contact angle measurements, roll‐off analysis, and fogging tests.

Formation of Carbonyl and Carboxyl Groups on Cellulosic Pulps: Effect on Alkali Resistance

BioResources, 2014
Ozone bleaching generates carbonyl groups on the cellulose polymer when applied to unbleached kraft pulps. This suggests that pulp fully bleached with a totally chlorine-free (TCF) sequence may contain more oxidized groups than standard elemental ...

Controlling Temporally and Spatially Homogeneous Temperature Distribution of Paper Substrates by Biogenic Phase Change Hybrid Material Coatings

Advanced Materials Interfaces, Volume 12, Issue 3, February 3, 2025.
Phase change materials (PCMs) can absorb energy during their melting process, whereby heat, for example, is attenuated as it passes through. In this study, a mixture of ethylene glycol distearate (EGDS) and cellulose stearoyl ester (CSE) was used as a PCM in paper without the need for encapsulation.

All-cellulose composites from unbleached hardwood kraft pulp reinforced with nanofibrillated cellulose

Cellulose, 2013
In the present work, nanofibrillated cellulose (NFC) from bleached eucalyptus pulp was prepared, characterized and used as reinforcement in an unbleached eucalyptus fiber matrix. First, the NFC was fabricated through TEMPO-mediated oxidation and characterized for the degree of polymerization, water retention value, cationic demand and carboxyl content.

Kappa Number Prediction of Acacia melanoxylon Unbleached Kraft Pulps using NIR-PLSR Models with a Narrow Interval of Variation

BioResources, 2014
A total of 120 Acacia melanoxylon R. Br. (Australian blackwood) stem discs, belonging to 20 trees from four sites in Portugal, were used in this study. The samples were kraft pulped under standard identical conditions targeted to a Kappa number of 15.
